Title: Communication network connection test method
Inventor: URATA ATSUSHI
IPC: H04L12/26
Filed: 1995-02-27
Abstract: PURPOSE: To confirm the normality of a communication network by instructing a control signal to the communication network with the use of a signal channel and transferring the end-end communication information with the use of the communication channel. CONSTITUTION: A connection test directing part 2 in an operation system 1 sends the command data of executing the connection test through a communication data transmission/reception control 11 and an ISDN network 10 to an originating/incoming testing device 21A. A control part 29A executing the connection test in the accepted testing device 21A sends a trigger signal from a test terminal 23A through a communication path IF part 24A, communication path 27A common line signal device 28A, and communication line signal network 30 to an SCP 31. Then a direction part 2 of the system 1 accepts a response signal from a service control node SCP 31, and the TDP information is set and the connection instruction with a monitor telephone set 3 is sent from the control part 29A to the terminal 23A.  Further, when the end-end communication information is sent by using the communication channel, the normality of the communication network 30 can be confirmed.

Title: Radar calibration device
Inventor: MICHIGUCHI YOSHIHIRO
IPC: H01P1/12
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a small and cheap radar calibration device capable of accurately calibrating the distance to other vehicles and relative velocity. SOLUTION: During calibration, wave transmits through an oscillator 101, a turnover switch 103, a directional coupled device 106 and a waveguide 107, reflects at a reflector and reversely transmits through the waveguide 107 and the directional coupled device 106 to a processor 105. It compares the preliminarily obtained position and velocity of the reflector with detected values of position and velocity that are obtained from the frequency difference between transmission wave and reception wave. The oscillation characteristics are controlled so that they coincide. By this, the fluctuation and distortion of the oscillator oscillation frequency are corrected so that the distance to a detecting object and the velocity of the object are correctly detected.

Abstract: PURPOSE:To allow the response speed required for TVs by impressing a voltage by each of picture elements through active elements to a ferroelectric liquid crystal element which is so oriented that the stable state of orientation while the voltage is not impressed is only one state. CONSTITUTION:A Ta2O5 film 12 is formed on a glass substrate 10 having a transparent conductive film 11 and polyimide is applied by a spinner thereon. The coating is subjected to a rubbing treatment after baking to form an oriented film 13. On the other hand, thin-film transistors and electrodes 16 for displaying are disposed on the substrate 22 and the Ta2O5 film 15 is formed thereon. The oriented film 14 is then formed by applying the polyimide and subjecting the coating to the rubbing treatment after baking. The substrates 10 and 22 are disposed to face each other via spacer beads 23 and a ferroelectric liquid crystal 24 is injected. This liquid crystal is monostable and the molecular axis rotates up to the specified position by a voltage. The complete halftone and the response speed required for TVs are thus obtd.

The 1st DA receives a signal from input lines M1, M2 and gives an output from output lines T1, T2. The 2nd DA consists of the amplifier TRs Q3, Q4 and the load resistors L3, L4 and is connected to the power lines E1, E2 via a constant current source H2 and a resistor 5. The 2nd DA uses the input lines M1, M2 of the 1st DA in common and crosses outputs from the loads L3, L4 to apply the result to gates of the buffer TRs QB2, QB1 of the 1st DA. Thus, even when the frequency of the input signal is higher, the output is not decreased and the frequency characteristic is improved.

Abstract: PURPOSE:To perform the chain changing work fruitfully. CONSTITUTION:A timer section 11 accumulates the time when at least the signals of a master station and slave stations are not continuously detected by a LORAN signal detection section 7, and whether the accumulated time is in the first state that the fixed period elapses or the second state otherwise is judged. A GRI selection section 5 selects the chain on the best geometrical condition among near chains obtained by a near chain calculation section 4 and sets a memory section 2 to the second state when the content of the near chain is changed. A GRI set section 6 sends the chain selected by the GRI selection section 5 to a LORAN signal detection section 7 as a specific chain when the memory section 2 is set to the second state and sends another chain when otherwise. A station selection section 8 selects two best slave stations among the chains set by the GRI set section 6 and resets the timer section 11 when the station selection is changed. An initial reset section 1 sets the memory section 2 to the second state when a power source is turned on.

Title: Displacement measuring instrument
Inventor: IWAMOTO KATSUJI
IPC: G01D5/30
Filed: 1990-02-22
Abstract: PURPOSE:To obtain this instrument which is hardly affected by disturbance and can take an accurate measurement even if an optical fiber connector is loaded in halfway by carrying a 1st light which is reflected by a pressure receiving diaphragm and a 2nd light which is absorbed by one optical fiber for light reception. CONSTITUTION:When the pressure receiving diaphragm 1 is deflected responding to pressure, the quantity of light of a photodiode(PD) 15 is increased and a reflected signal voltage is boosted. The quantity of reference light is still constant and a reference voltage which is converted into an electric signal by a PD 16 is constant, so an output corresponding to pressure can be outputted by arithmetic processing 17 based upon the reflected signal and reference signal and output adjustment processing 18. When the optical fiber is bent owing to disturbance, the reflected signal voltage and reference signal voltage vary similarly since the signal light and reference light are propagated in one optical fiber 11, and variance caused by the disturbance can be removed by the arithmetic processing 17. Further, even when the optical fiber connector is inserted halfway, only one optical fiber is used, so the influence of the alignment is hardly exerted.
